Question

25% of 20 liters of milk bought by Ramu is ___. ​

Answer 1

Step by step Explanation:-

1 litre milk cost is=20 Rs.

then,25 litres milk cost is=25 ×20= 500 Rs.

because 3 litres milk are lost by leakage..

Hence,,,Rest milk=25 ltr-3 ltr=22 ltr

The remainder is sold at 25 Rs /litre

hence,, 22 litres cost is=22×25=550

because,,,the selling price(SP) is great than cost price(CP)..hence,,He benefited..

Hence,,

profit=550-500=50 Rs.

Profit %=

\begin{gathered}\frac{profit \times 100}{cp} \\ = \frac{50 \times 100}{500} \\ = \frac{50}{5} \\ = 10\%\end{gathered}

cp

profit×100

=

500

50×100

=

5

50

=10%
